Abstract
Description
-
- a) providing an opposed-facing pair of first and second tension supports such as yokes having a parallel pair of flexible first and second elongate members such as cables extending therebetween in spaced parallel array, and a means such as actuators for tensioning the first and second elongate members so as to selectively draw the first and second tension supports toward each other,
- b) providing first and second conductor mounts such as grips, which cooperate with the first and second tension supports and mounting the first and second tension supports in spaced apart array to and along a conductor segment of a conductor to be serviced so as to extend the conductor segment along and substantially medially between the first and second elongate members,
- c) drawing the first and second tension supports toward each other to thereby de-tension the conductor segment to allow for the service.
